I have an old Satoh Beaver with a Johnson Workhorse 10 FEL which has the traditional two lever loader control (it has downpressure etc)

Anyhow, on to my question. I have an increasing leak in the valve/levers control box (dont really know what it is called) which leads me to believe I have blown an O ring or damaged a valve. It seems to be getting worse, even when I dont use the loader - as the hydraulics are live. How do I open up the valve body? there are two levers, and four quick connect lines coming out of the top. I see no obvious bolts to take the thing apart.

This is my first compact with a loader, so I am new to hydraulics.
